We say "This big or this long" we can't say this much big or long, but is there any condition where these 2 can be used together?
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
If you mean 'much' and 'big/long', no.
But if we want to say "this much talent or this much tolerance"or something like this?
Yes. Note that 'talent' and 'tolerance' are nouns.
