A beta particle is an electron, with a mass of approximately 1/1840 of a proton
Yes; they simply have opposite charges.
They do, it's just such a small contribution that in practice it's usually negligible. It takes about 1800 electrons to equal the mass of one proton.
The mass of a proton and neutron are pretty close. So the ratio will be roughly 1 to 1 (or 1:1). The neutron is heavier and if memory serves it is exactly the mass of an electron heavier than a proton. Note it takes around 1820 electron to equal the mass of one proton.
The mass of a nucleus varies according to the atomic number (ie according to what element it is). For hydrogen , the simplest nucleus, the combined mass of the one proton and the one neutron would be equal in mass to 3672 electrons.
