I've had a bit of an accident and the car you leased to me this morning is now a burnt out shell 3 I've had a bit of an accident and the car you rented to me this morning is now a burnt out shell 5 I've had a bit of an accident and the car you hired to me this morning is now a burnt out shell 1 There may be fixed allowances payable for accommodation and meals or firms may reimburse reasonable expenses 5 There may be fixed allowances payable for accommodation and meals or firms may recover reasonable expenses 1 There may be fixed allowances payable for accommodation and meals or firms may cover reasonable expenses 4 The use in some of your sentences would depend on the particular situation. A lease in generally a long term transaction for months or years. You can lease a car rather than buying one but when traveling you would always "rent" a car or "hire" a car. The verbs "lease" and "rent" can be used by either party. (Ex. You can lease/rent me an apartment. I can lease/rent and apartment from you. However "hire" is used strictly by the person taking the car. I hired a car for the day.( correct) You hired me a car. (not used) Also the verb "to hire" is not used in this way in the United States. We use "rent". In your second example you would probably go with "the company will reimburse you for expenses." The differences in these words are : "Reimburse" means you will pay for it and the company will pay you back afterwards. "Cover" generally means the company will pay the expense and you will not have to. "Recover" is used when we regain something that was lost. I don't think this is what you have in mind here. Sorry for the long response but I hope it helps explain the differences in the words. Good luck!
