Do neutron star, pulsars, magnetars etc. have solar flares like the sun or do they have sun spots like the sun or do they have solar winds and if they do have any of those types of weather, what are they called?

These stars are not like the Sun - so the short answer is "no".
There is "stuff that happens on and about them", some of which could be considered as analogous to some solar "weather" stuff ... you should be able to read about them in books and online.

The answers could occupy an entire semester's astrophysics course - what have you don to try to find the answers yourself?
i.e. Do you know what a starquake is and how they happen?

I do think star quakes fall in the category of weather but they do hit 23 on the recner scale and can mess up a magnetars magnetic field.

So the answer is "no" - you don't know how they happen?
If you want to know if a starquake can happen on a particular class of star you should first learn about them, then see if the conditions exist in some form on the particular class in question.

There exists a plasma filled magnetosphere around neutron stars. So, as Simon Bridge says, the answer is no, however there occurs some sort of events similar but not the same as that also occurs in a main sequence star (like sun). For example there are pulsar winds, gamma ray bursts etc. The starquakes are totally different than the magnetospheric events since a starquake occurs as a consequence of crunches of the neutron star crust. The main reason of the answer "no" is that the typical magnetic field of a neutron star is much much higher than a main sequence star (between $10^8-10^{15}$ Gauss). You can study all of this "weather" stuff under the subject of "neutron star magnetosphere", I guess.
