Can i charge an LiFePo4 32650 cell using an 18650 li-ion charger
No it will not. Trying to do so will damage your battery - as it is a LiFePO4 chemistry, it might not burn down your house, but still, overcharging batteries is dangerous.
Your charger has a 4.2 V maximum charge voltage and 650 mA charge current.
Your website actually tells you what you need to know for charging the battery:

Cutoff voltage (at which voltage must the charging stop): 3.7 V
Maximum charge current: 1C (which is not Coulomb but indicates it can be charged at 1 times the capacity rating, so for a 6000 mAh battery like this it means 6000 mA maximum charge current

If you want to know if charging works you have to stay below the limits of the battery. So it will fail because it will charge to 4.2 V instead of only 3.7 V.
