I'm reading and translating Matthew Henry biography, I encounter this
paragraph:

The first important news which reached him in the great
city was, that the king had empowered certain individuals
to grant licenses exempting the several persons, named in
a schedule annexed, from prosecution, or molestation.
1. For not taking the oaths of allegiance and supremacy ;
or 2. Upon the prerogative writ for ,£20 a month, or upon
outlawries, or excom. capiend. for the said causes; or 3.
For not coming to church; or 4. For not receiving the
sacrament; or 5. By reason of their conviction for recusancy,
or exercise of their religion, a command to stay
proceedings already begun for any of the causes aforesaid.
The price of one license was '£10 for a single
person; but if several joined, the price was £16 ; and
eight might join in taking out one license.

I'd like to know:

1) the persons listed under 1-5 would be granted licence, is it right?

2) what does "Upon the prerogative writ for £20 a month, or upon
outlawries, or excom. capiend. for the said causes" mean? I don't understand
what do "the prerogative writ for £20 a month" and "excom. capiend" mean?

The time for the above mentioned matter is around 1687, this book
tells me.

Thanks for any help.
