In general it looks OK, but there is one thing that looks wrong:

0.04412 L X .092991 M =.004103 moles of HCl

the average morality of three trials of HCl came to .093298 M HCl

So, 0.092991 or 0.093298?

Its 0.092991 not 0.093298, so did I do it correctly or no?

As I wrote - everything else looks OK.

Ok thank you  its just that "looks ok" doesn't sound very reassuring lol
Thanks again for all your help

You still need the calculations for the other two trials and an average...

The setup for your calculations is correct now. I didn't run the numbers through the calculator, but barring possible error in calculation, it's right.

the soda ash in analysis was assumed to be pure Na2CO3.if some of the Na2CO3 is replaced by an equal number wights of NaHCO3,how would the volume of acid change from  the phenolphthalein end point to the methyl red end point ? 2)if some of the Na2CO3 were replaced with an equal number of weight of NaOH,how would the volume change ?
