I'm noticing that your evening routine has three abdominal exercises and zero back exercises -- you might want to consider adding back bridges or supermans to balance your core. I would recommend skipping crunches and situps -- they're bad for your back/posture and they're ineffective at developing abdominal strength or endurance. Instead, I'd recommend planks, since they strengthen the abdominal muscles while emphasizing good posture. The hanging leg raise is also a great ab exercise, since it works the whole abdominal chain without loading the back.

Your evening workout also only has an upper body push motion (pushups) which is neglecting your pulling muscles. I would recommend adding rows or chinups to balance out the joint. Joint strength imbalance is responsible for many injuries that people experience, and it's very common to be stronger at pushing than pulling due to the higher status of push exercises in Western culture.

For the office routine, planks get my recommendation again. If you want to invest a bit of money, the ab wheel can be used for rollouts which are extremely effective. That shouldn't have you touching the floor too much if you put some padding under your knees.
