What about default WordPress cropping? Does it work? Maybe the problem is in the access permissions to /uploads directory.

Other possible issue – do you have PHP image manipulation modules installed and activated?

You can try this plugin: https://wordpress.org/plugins/bp-disable-activation-reloaded/
But you should not do this – anyone will be able to register with fake emails.

This is a required field
On my screenshot here https://monosnap.com/file/GLDmV6D1PVbSwtSEB7rDVQatZKcC93# that text (This field is required) is just a field description.

It seems to me, that you are using the old version of BuddyPress. What is it?
On newest versions required fields are marked with the text (required), and not asterisk.

I believe this theme compatibility problems is better to discuss with theme authors. I googled and found several issues with this particular theme, that users can’t fix by themselves.

BuddyPress tries to work with all possible themes, and it’s very hard to be good with everyone. In my opinion, theme authors should check their themes with popular plugins.

All fields in default Base (Primary) fields group will appear on registration page. Those fields can be required or not, based on Required setting for fields: http://take.ms/soyY7
Here is how it looks in a list of fields in admin area: http://take.ms/tMI8w

So just modify that setting for fields, that you need always be filled with data, to Required.

The easiest solution is to use JavaScript here.

Based on this: https://css-tricks.com/snippets/jquery/target-only-external-links/
You can do like this:
jQuery(document).ready(function(){
jQuery('#activity-stream a').filter(function() {
return this.hostname && this.hostname !== location.hostname;
}).attr("target", "_blank");
});

Separate languages – no, because all the plugins (and BuddyPress is a plugin) use the same language as the system. Because of the amount of hooks/filters in WordPress it’s nearly impossible (or very time and/or resources consuming) to create a reliable solution, that will switch language for plugins, but will not for WordPress.

BP Default Data does nothing on plugin activation and deactivation. It has own clearing routine, you can see it here: https://github.com/slaFFik/BP-Default-Data/blob/master/bp-default-data.php#L643

Are you on MultiSite?

You are right, my bad.
But that’s a good (handy) plugin idea. Noted to self, perhaps will create it soon (will update this topic).

All fields that are in the first Base fields groups will appear on registration page.
So you can just move those fields to another fields group, that you can create on this page /wp-admin/users.php?page=bp-profile-setup using this link http://cosydale.com/wp-admin/users.php?page=bp-profile-setup&mode=add_group.

Just navigate to this page: /wp-admin/users.php?page=bp-profile-edit&user_id=1802
where 1802 – is the ID of that user. Also, all usernames on this page /wp-admin/users.php?page=bp-signups are links to profiles. So you can open there Extended profile link at the top.

Here is the direct link for BuddyPress RC 1.
