Very nice, I quite like these. Have always though the logos would look better stacked for some uniformity - even if they did keep their individual typeface for the channel name which you’ve done.
How would you possibly improve the ones for News First / Sport etc?
I really like the font they use for Speaks / Play, and have always wanted to see that used as a mock for all of the networks stations and services.
Personally I’d like to see them use a 10 Sport watermark for all sports programming airing on multis or 10 play, but I think what you’ve done there is more realistic.
