How many speakers can be hooked up to this model. null

You can plug multiple speakers into an output as long as their ohm load is not too low, I use 2 dual 8" Celestion towers that are 80 watts a piece and it sounds great. I would not advise using more than 4 towers at once as it will put a strain on the system (even though 8 is possible using both A and B channels with 2 towers in series or parallel).

Its not a question of how many speakers, but more importantly not presenting an unsafe load impedance that falls below Yamaha's stated value. Power from the receiver is a product of voltage (i.e. the driving force) times the current (i.e. the resulting flow of electrons). So if one 8-ohm speaker draws a certain amount of current then when another 8-ohm speaker is connected making the total load drop to 4-ohms (i.e. a parallel circuit connection) then TWICE the amount of electron flow (i.e. current) will be demanded from the receiver's output circuits. Can this receiver's final output transistor withstand this higher current flow safely? There are many reputable 'Speaker Selector Switch Boxes" on the market that will safely allow a large array of speakers to be connected to this or any other amplifier, but the trade off will be less sound pressure level when there is an increase in the number of speakers. These boxes are dividing the 100 watts of power 'X' number of ways. For a rough example, 100 watts divided among two speakers will yield 50 watts per speaker. But that same 100 watts divided by 10 speakers will only yield 10 watts per speaker. So naturally each of the ten speakers will not be as loud as the previous set up where only two speakers were sharing the 100 watts of signal power.
