Both wna i aros and bydda i'n aros mean I will stay. But this does not mean that the two forms of the future tense are entirely interchangeable. Both tend to be used in different contexts and to convey slightly different meanings.

Bydda i'n aros = I will stay. / I will be staying .

Wna i aros =  I will stay.

Consequently if you are referring to an action that will be ongoing at some point in the future you might want to use bydda i'n.

e.g. Bydda i'n aros yn y gwesty. = I will stay / be staying at the hotel

If on the other hand you wish to express an intent to carry out a specific action at a specific time you might more naturally employ wna i .

e.g. Wna i aros yma heno. = I will stay here tonight.

As you can see from the above examples these forms of the future mirror the difference in the English future tense between I will and I will be . Whilst these differences do not, perhaps, prevent the two forms from being more or less interchangeable there are contexts and circumstances where one or the other is required.

1. Since it means I will be , bydda i'n can be used with adjectives e.g.

Bydda i'n dawel. = I will be quiet.

Byddwch chi'n falch. = You will be pleased / proud.

( Note the soft mutation after yn )

2.  Similarly bydda i  can be used with prepositions. e.g.

Byddwch chi ar y bws. = You will be on the bus.

Bydda i gyda chi. = I'll be with you.

( There is no connecting yn )

3. Wna i can be used to make polite requests or ask for favours. e.g.

Wnewch chi ofyn y cwestiwn? = Will you (please) ask the question?

If we substitute bydda in this context we would merely be enquiring whether someone was going to ask the question, not politely requesting that they do. e.g. 

Fyddwch chi'n gofyn y cwestiwn? = Will you ask / be asking the question?

Clearly the two forms of the future tense serve different purposes in this context.

4. Wna i can also be used to express resolve or determination, similar to English 'I will do my homework.' e.g.

Wna i orffen y ras . = I will finish the race.
