Can you try the arm32v7 image instead? Is this throwing the same errors?

my device doesn't have a user with UID 13.
But I got the same error with UID 0 (root) as well.
I'll try arm32v7 image
from docker-squid-proxy.

Hmm...Well there is definitely something wrong with permissions on your client. I've tested the arm32v7 image yesterday on my Raspberry and it was working fine. As I'm not able to look into your client to investigate myself, I'm afraid you have to find out yourself why this happens.
Some suggestions which could help.
=====
Please don't use any user id which could already exist inside the container. User id 0 is definitely already existing inside the container, because it is always the root user. You need to specify some user id which the container can use for a user named squid. Outside your container the user with id e.g. 13 doesn't need to be named squid. It can be any other user. The container dosen't care what happens outside as long as the permissions for the mounted directories/volumes outside are correctly set to be accessible/writeable by e.g. user id 13.
So best practice could be to create a new user (outside container) with a name you like (e.g. useradd -r -s/usr/sbin/nologin -M docker_squid). Then look inside your /etc/passwd and check which uid and gid this user got. Now change the permissions of your directories, you want to use as volumes for your container. And after that use those ids for creating the squid container.
=====
You can try to change the entrypoint of the image to /bin/bash -c 'while [ 1 == 1 ]; do sleep 10; done' or something else, which is running endlessly. This way you should be able to connect to the conatainer using docker exec -ti squid bash. Once you are inside the, newly created, container please run /start-squid.sh. It will most likely fail the same way as your logs above show, but this way you made the script create the initial directories/files. After that you can start to investigate why your permissions aren't working inside the container. So the hole create command should look like this (and yes, the arguments for bash are coming after the image name):
docker create \
--name squid \
-e TZ=Europe/Istanbul \
-e PROXY_UID=13 \
-e PROXY_GID=13 \
-v /docker/config/squid/etc:/etc/squid \
-v /docker/config/squid/etc:/var/log/squid \
-v /docker/config/squid/spool:/var/spool/squid \
-p 3128:3128 \
-p 3129:3129 \
--entrypoint /bin/bash \
distahl/squid:buster-arm32v7 \
-c 'while [ 1 == 1 ]; do sleep 10; done'
=====
Finally there is also an option for create, which should give your container all the privileges available, but this isn't good practice and should be avoided. Also, even if you use this option, you still need to make sure to use a correct user id and have set the correct permissions. So the option is: --privileged
from docker-squid-proxy.

2021/02/11 16:02:04| Removing PID file (/run/squid.pid)
I even tried to run squid container with changed entrypoint to /bin/bash then run ./start-squid.sh with the same result
I think there is problem with the start-squid.sh when trying to create spool dirs because when I disable caching in squid.conf squid container run without problem and squid logs access.log && cache.log copied to host volume directory ./../squid_log
update:
I started the container with these lines commented in squid.conf to be able to access the conatiner bash
# cache_dir ufs /var/spool/squid 500 16 256
# coredump_dir /var/spool/squid
# cache_effective_user proxy
then after the container started I uncommented the lines in squid.conf on host volume directory ./config/squid.conf to enable the cache again then what I did
cd /var/spool/squid
/usr/sbin/squid -z -f /etc/squid/squid.conf
1- the spool directories created and copied to host volume directory ./../squid_cache
2- the owner of volume host directories is squid:squid
3- the owner of container directories proxy:proxy
which means start-squid.sh failed to create spool directories for some reason
I stoped squid container then
sudo docker-compose up
