any help ;

I have read your question now a couple of times and it is not clear (at least to me) what you are asking.

Are you wanting to get rid of your XTAL to gain more input lines? If you do, with the use of RA4 you will have 3 more but have requested 4. Please clarify your request.

I now use 10 dipswitch as input (look at image) and i want to add more dipswitch.

also the ra4 and the mclr(ra5).
will i have problem if change the XTAL with internal OSC;
Sorry for my English.

you shouldn't have too much problem using the internal OSC as your application (for what i remind of) is not really timing critical. Go Go Go use the internal OSC and the MCLR pin as you wish, they're free!

The only thing you'll have to do is to change the config fuse.. see the FAQ

Sorry for my English

You don't want to hear my Greek My english is actually really poor myself too but who cares as long as somebody understand it

Yes you can use Ra4 as input.

No i don't speek Greek... i may understand few words here and there but... yiissh.. hehe as the english expression said ... it's Greek to me Quebecer french says... it's Chinese to me... i heard also something like It's Gobledagook to me. I guess it depend where you're located.
