I then had sex on February 11 with guy number 2. I am 8 weeks pregnant with a due date of November 5th is there anyway to tell who could possibly be the father?

Brief Answer:
Possibly from intercourse on Feb 11

Detailed Answer:
Hi dear,
I have gone through your question and understand your concerns.
Sexual intercourse within5-6 days of the starting of periods do not cause pregnancy as the ovulation timing is far.
The pregnancy is possibly due to the intercourse on February 11, which was day7 of your cycle.
Hope you found the answer helpful.

My cycle ended on February 10th. Isn't it true that sperm can stay inside you for up to 5 days? So if guy number 1 sperm was on February 8th and stayed inside would that out run guy number 2 sperm on February 11th?

Detailed Answer:
Hi dear, the intercourse on Feb 8 was in completely safe period, meaning there was no chance of pregnancy.
Moreover, the ovulation occurs around day 14, by which the sperms from the first intercourse are definitely dead, while there are chances that sperms from the second intercourse are still viable.Hope you found the answer helpful.

I looked at a calendar and it seems that my ovulation day should have been Feb. 19th which makes me wonder why my due date is Nov. 5th. still with the information above if I had sex with guy #2 on Feb. 11,14,and 16th and guy #1 on Feb. 8, and guy #1 pulled out on Feb. 18 and 19th(ovulation day possible) what would you think?
